NASA-Funded Research Discovers Life Built With Toxic Ch

NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth. Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic f

Structure-Function Studies of the Neisseria gonorrhoeae

The major outer membrane porin (PorB) expressed by Neisseria gonorrhoeae plays multiple roles during infection, in addition to its function as an outer membrane pore. We have generated a panel of mutants of N. gonorrhoeae strain FA1090 expressing a variety of mutant porB genes that all function as porins. We identified multiple regions of porin that are invo

WHAT DOES IT TAKE TO BE SEXY?

What makes a sex? There are two answers to this question, the master regulators that tell organisms which sex they should be and the downstream genes that encode the molecules that make sexual behavior possible. Answering these questions is easier in the brewer’s yeast, Saccharomyces cerevisiae, where there are two mating types, called a and alpha, and si

Angelo Miguel Figueiredo, Sara B.-M. Whittaker, Stuart

The diversity of possible conformational states makes it challenging to obtain a structural description of how proteins fold. Clusters of hydrophobic residues in unfolded states of a protein help determine interatomic contacts in the early stages of folding. Here, the authors describe dynamics of an Im7 variant designed to increase the helical propensity of
